87 5.0 aod

The trans in my 87 5.0 is slipping. It has a floor shifter.
What other cars can I get the trans from?
I need to save some money, that's why I'm keeping it auto for now.

Thanks in advance

Mustang. Almost anything else will be column shift, and the shift lever on the side of the trans is configured 180 from how yours is.  You might be better off having the trans gone through.

To add to what TFYK posted: the Stang AOD is a little bit beefier than your stock trans. If you have it rebuilt, specify replacement parts for the Stang's version. I think they have an extra clutch or 3 for either 3rd or OD....I used to know without any uncertainty, but it's been a long time since I've had to use the knowledge. Google will give you some mileage here..

I'd probably go with having the AOD rebuilt/shift kitted, and epoxy mod done as opposed to a salvage yard trans with a 30 day warranty, etc. I've never had any good luck with a transmission that's sat for a period of time "dry". Seems like they've always went bad on me, and in several different vehicles, as well.

If you MUST go sping for a trans, get a 4R70W from a 97-03 F-150 with a 5.4.  It's a tough one to get, but you can transfer the entire stack and end up with the toughest possible AOD with lighter stronger parts, lower friction bearings, a wider OD band and a wide-ratio mod that really makes first and second a happier place to be.  Not to mention a much higher torque rating.  Use a V6 AOD torque converter.

can anyone confirm that the v6 aod TC is better? if so why?

Possibly higher factory stall rating and less likely to be balooned due to some punk beating the brakes off of it.

SOMEWHAT more loose? That's a huge difference! A difference that would really help out an H.O.-spec or GT40-spec built 5.0.
It seems incredibly rare, but there were indeed 3.8 V6 Fox Mustangs? I know I've seen ads for Fox Ford LTD's or Merc Marquis's with a V6. They would be an AOD as well? So you could simply go to Advance Auto/Rock Auto/etc and order a V6 converter for one of these vehicles and boom, 2600 RPM converter? Seems too good to be true, but if it is, that's an awesome money-saver.

Also the bit about Mustang AOD's. That is news to me as well. I have heard of swapping 4R70W bits in. Didn't realize the entire rotating assembly was plug-and-play though.

Fox Mustang only had 3.8L for a few years in the early 80's, but you can get a 3.8L AOD tc from an LTD, Tbird (incredibly common) etc. 
The 4r70w stack is "more or less" plug and play.  There's a couple places where you'll want to keep 1 or 2 original AOD stack parts.  I don't remember specifically, but as with any auto trans work, you'll want a background before you dive into one, otherwise you can take your AOD and your 4R70W to a trans shop and tell them, "here, put any part of the 4R that's better than the AOD into the AOD".  You won't be able to use the 4R70 valve body or case, so think about a shift kit if you're planning more than 300HP.  You'll want to use the bearings, the shafts, the drums, pistons, servos, bands, and planetaries.  Always use new clutches and steels, if you have the choice, use clutches that have the grooves in them, they channel fluid out better and give crisper quicker shifts.  If you use the ungrooved clutches, you take longer to push the fluid out, and the clutches drag against the steels longer before they get a good bite.
